GEORGE FROST, JR, OF PATERSON, NEW JERSEY.

MACHINE FOR MAKING BANDING.

SPECIFICATION forming part of Letters Patent No. 759,089, dated May 3, 1904.

\ Application filed October 1'7, 1903. Serial No. 177,484. (No model) To all whom it may concern.-

Be it known that I, GEORGE Fnosr, Jr., a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey,have invented new and useful Improvements in Machines for Making Banding, of which the following is a specification.

My invention relates to new and useful improvements in machines for making banding, and more especially topped or hat-d twisted bands. Heretofore in the useof machines of this character it has been necessary to employ two operators, one of whoin'turns the crank of the machine in order to twist the strands of the band, while the other carries a spindle or similar device which is held between the strands and is employed for retarding the .twistingoperation, so as to obtain a tight twist. It has been found, however, in the use of this form of machine that unless both operators work at a uniform speed there will be considerable variation in the twist and the length of the bands when finished. 1

The object of my machine is to provide mechanism adapted to be driven by any suitable power and having automatic retarding means for producing a uniform twist of the material independently of the speed of the operating mechanism.

With the above and other objects in View the inventionconsists in employing a novel arrangement of adjustable gears for transmitting rotary motion in the same direction from a power-shaft to hooks which are spaced apart. The material to be twisted is engaged by these hooks and is looped upon a swivel, and inllGlPOSGd between the swivel and the twisting mechanism and between the strands of the material is a retarding device which is adapted to be moved longitudinally upon a bed provided therefor by the pressure exerted by the The movement of this retarding device is controlled by weights, springs, or other suitable devices.

The invention also consists in the further novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which Figure 1 is an elevation of my improved machine, showing the retarding device subsequent to the starting of the second twist, certain parts of the machine being omitted. Fig. 2 is an elevation of the twisting mechanism and the retarding device in position at the end of its movement, the frameof the gearing being shown in section. Fig. 3 is an enlarged section on line 33, Fig. 1. Fig. 4 is an enlarged section on line 4 1, Fig. 1. Fig. 5 is a section on line 5 5, Fig. 2; and Fig. 6 is a plan view of the twisting mechanism.

Referring to the figures by numerals of reference, 7 7 are standards in which is journaled a power-shaft 8, having a fixed pulley 9 and a loose pulley l0 thereon, adapted to be rotated by a belt 11 or any other suitable means. To one of the standards 7 are secured plates '12, which are spaced apart in any suitable manner, and arranged between these plates and upon the shaft 8 is a drive-gear 13. This gear meshes with intermediate gears 14:, journaled on arms 15, which have longitudinallyextending slots 16 therein for the reception of bolts 17. These arms are adapted to be clamped in adji'isted positions upon the bolts by means of nuts 18 or in any other suitable manner, and meshing with each of the intermediate gears 1 1 is a gear 19, secured to a stem 20, which is journaled within the plates 12. Each stem has a hook 21 at its inner end and in position above a bed 22, which is supported at one end upon one of the standards 7. The other end of the bed is supported by a suitable bracket 23 provided therefor, and arranged on this bracket are pulleys 2 1 and 25. This bracket can be secured in place in any suitable manner. It is preferably fastened to thewall of the structure in which the machine is located, as shown in Fig. 1.

A carriage 26 is slidably mounted upon the bed 22 and has flanges 27, which overlap the side edges of said bed and prevent displacement of the carriage. This carriage has a block 28 thereon, which is centrally recessed, as shown at 29. A plunger 30 is slid-ably mounted within this recess and normally held projected from the top thereof by a spring 31, which is interposed between the plunger and the bottom of the recess 29. A chain 32 or other flexible device is connected at opposite ends to the bottom of the recess 29 and the plunger 30, so as to limit the outward movement of said plunger. A retaining-strip 33 is pivotally mounted upon the upper end of plunger 30 and is adapted to project from one side thereof, as shown in dotted lines in Fig. 4. A loop 34 extends rearwardly from block'28 and is adapted to be engaged by a hook 35, secured to one end of a cord or other flexible strip 36, which extends longitudinally of the bed 22 and under the pulley 24 on the bracket 23. This cord then extends upward over a pulley 37, which is suitably supported above the bracket 23, and the depending portion of the cord is provided with a desired number of weights 38. I A spring 39 is fastened to the bracket 23 in any suitable manner and is connected to a cord or other flexible strip 40, which extends around a pulley 41, suitably secured above the bracket 23, and thence downward under pulley 25. This cord is provided at its end with astem 42, which is swiveled in a hook 43, and a cylindrical weight 44 is loosely mounted on the strip and is adapted to hold the same normally depressed, but spaced from the cord 36.

In using the machine herein described the material to be twisted is formed of a desired length, and the ends thereof are fastened to the hooked stems 21. The material to be twisted is then placed in engagement with the swiveled hook 43, and the block 28 is moved into position adjacent the swiveled hook and with its plunger 30 in position between the strands of the material. The retaining-strip 33 is then swung to one side and into position over one of the strands, and the device is ready for use. Power is imparted to the shaft 8 by shifting the belt 11 from the loose to the fixed pulley,and the gear13 is thus rotated and transmits rotary motion through the intermediate gears 14 to gears 19. These gears will be revolved in the same direction, and the material will be turned so as to produce what is technically known as the first twist. As the stems 21 continue to rotate the second twist will be made, to wit: the swiveled hook will be turned and the strands will be twisted about each other, commencing at the swiveled hook 43. As this operation continues the twisted strands will press against the plunger 30, and this pressure will ultimately be sufficient to raise the weights 38 and move the carriage 26 longitudinally upon the bed 22. It will be understood that this carriage will be moved along the bed as the twisting operation continues, and the retarding action exerted thereby will be the same at all points, and a uniform twist will thus be obtained. When the entire rope band becomes twisted, the movement of the carriage will stop and the operator stops the machine and then swings the retaining-strip 33 from position over one of the strands and presses downward upon the plunger, thereby removing it from position between the strands, and the weights 38 will promptly return the carriage to its normal position ready for the repetition of the abovedescribed operation. The carriage stops in its normal position when the weights 38, controlling its movement, reach the limit of their downward movement. With a machine of this character it will be seen that but one operator is necessary, his dutybeing to place the carriage in proper position prior to the twisting operation and releasing the same subsequent to said operation, so as to permit it to automatically return to its normal position. I do not desire to restrict myself to the use of two strands where this machine is employed, for, if desired, bands of three or more strands may be formed thereby. The speed of rotation of the stems 21 can be regulated by employing different-sized gears 19. The slotted arms 15 permit the intermediate gears 14 to be adjusted backward and forward, so as to mesh with gears 19 of different sizes. The spring 39 permits the swiveled hook 43 to slightly movelongitudinally during the twisting operation to allow for shortening of the material resulting during such operation.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.
